제목 : AB-PLC Less Than Instruction [LES]
|
[LES]는 Less Than Instruction 의 약어다.
비교 명령들은 좀 간단 하네요.
Source A [N7:6]의 데이터 와
Source B 데이터 정수 775 비교 해서
Source A 보다 Source B가 크면 출력 Coil On
Source A < Source B
아 쉽다 거져 먹을 때도 있내 ㅋㅋㅋ
The LES instruction is used to test whether one values is less than another. If source A is less
than the value at source B, the instruction is logically true. If the value at source A is greater than
or equal to the value at source B, the intruction is logically false.
The symbol for the less than command is illustrated above. The LES command is placed on the
left side of the rung to determine if a rung will be true or false for an output command. There are
two parameters to enter Source A and Source B:
Source A - must be a Address.
Source B - can be either a program constant or an address. Negative integers are stored in
two's
complemntary form.
